Plan ahead and have several pumpkins cleaned, with pre-carved mouth and eyes. Guests can select a prepared nose, ears or hat made with construction paper, and secure additions in place with toothpicks.
Place electric or flameless candles in jack-o-lanterns for extra party lighting.
Create masks when guests first arrive to put everyone in the Halloween mood. Supply construction paper, ribbon, markers, etc.
Turn an old favorite into a Halloween scream by pinning the tail on the black cat, or neck bolts on the Frankenstein, the bandage on the mummy, or the fangs on Dracula.
Have your guests guess the body parts. Put items in a sealed shoebox with a small opening at the top. Use peeled grapes for the eyeballs, any shortly-cut pasta (cooked, drained and cooled) for the brains, and celery sticks for skeleton bones.
"Ghosts around the Campfire" is as easy as musical chairs with the right music.
Invite guests to come as their favorite animals, as clowns or as storybook characters.
Select a few simple games, read spooky stories, ask the children to tell jokes or perform magic tricks for entertainment.
